[Cocco] I woke up in a strange new world [Full Color]

A big brother wakes up to a nightmare of his little sister's design: he's starting kindergarten today, and she's already squeezed him into a frilled mint romper, pink heart bow, and white tights while she wears the sailor uniform. Hand in hand on the walk to school, her doting praise strips away his dignity until he's wetting himself and cooing 'Mommy' at her — then she whips out the fat, throbbing cock she's been hiding and makes her onii-chan worship it with tears and drool streaming down his flushed face. She finishes breaking him in by pinning him down and riding him cowgirl, tongue lolling as he weakly insists he's the big brother and the strong one, before the lights go out on him curled in bed, dreading and craving whatever tomorrow brings.
